Basically sax is a serial API and dom needs the whole document model in order to process stuff.....<br />
<br />
if you have a large database or distributed datbases containing lots of info, use sax.....it's way quicker.....<br />
<br />
if your documents or database are relatively small use dom....<br />
<br />
so in a b2b situation I nearly always go for sax unless you are dealing with a small vendor....<br />
<br />
I hear the new apache/perl validating parser is pretty good for DOM, so perhaps you should check it out.....<br />

Can anyone discuss, in detail, the advantages or disadvantages of using SAX to parse an XML file rather than DOM? &nbsp;Are there any particular qualities that a file containing XML should have which would make it more suitable for one or the other???

SAX vs. DOM

Extensible Markup Language (XML) refers to the encoding of documents such that they can be read by both machines and humans. XML documents use tags to show the beginning and end of a set of data. XML is used extensively on websites to show volumes of data, and is the default for a number of office productivity suites. This topic includes discussions of XML-related technologies, such as XQuery (the XML Query language), XPath (the XML Path language), XSLT (eXtensible Stylesheet Language Transformations), XLink (the XML Linking language) and XPointer (the XML Pointer language).
